A. The base revenue control limit for each school district for fiscal year 1980-1981 is computed as follows:

1. 1. Add the amounts in the fiscal year 1979-1980 budget effective May 15, 1980 for general operating and special education.

2. 2. Subtract the following budgeted revenues from the sum obtained in paragraph 1 of this subsection:

   1. (a) Tuition paid for attendance of nonresident pupils.
   2. (b) State assistance as provided in section 15-976.
   3. (c) Special education revenues as provided in section 15-825, subsection D and section 15-1204.
   4. (d) Proceeds from the sale or lease of school property as provided in section 15-1102.
3. 3. Add the increase in the base support level from fiscal year 1979-1980 to fiscal year 1980-1981 to the difference obtained in paragraph 2 of this subsection.

B. The equalization factor for each school district is computed as follows:

1. 1. Divide the sum obtained in subsection A, paragraph 3 of this section by the base support level for fiscal year 1980-1981.
2. 2. Subtract 1.0 from the quotient obtained in paragraph 1 of this subsection to obtain the equalization factor.

C. The revenue variation factor for each fiscal year is as follows:

1. 1. For fiscal year 1981-1982, 0.80.
2. 2. For fiscal year 1982-1983, 0.60.
3. 3. For fiscal year 1983-1984, 0.40.
4. 4. For fiscal year 1984-1985, 0.20.

D. The base revenue control limit for each school district during the five years in which the equalization plan is in operation is computed as follows:

1. 1. Multiply the equalization factor by the revenue variation factor for the applicable year. Beginning with fiscal year 1983-1984 if the resulting product is less than negative 0.08, use negative 0.08 for computation purposes as provided in paragraph 2 of this subsection.
2. 2. Multiply the product obtained in paragraph 1 of this subsection by the base support level for the applicable year.
3. 3. Add the base support level for the applicable year to the product obtained in paragraph 2 of this subsection.
